A doorway under an escalator in a mall makes an unlikely entrance to a bar that claims to offer a ‘unique experience of New York and London glamour with added transatlantic style’. The boast comes from this glitzy venue at the O2, which was conceived by airline partners Delta and Virgin Atlantic. The place resembles a futuristic VIP departure lounge circa Jane Fonda in Barbarella. Expect to pay up to £12 for cocktails that might include Flying Lady (a limoncello Cosmopolitan), Aviation, or 30,000ft (a Woodford Reserve bourbon and maraschino cherry Old Fashioned). Wines from £25 and craft beers are served with surf, turf or dairy sharing platters, plus anything from Brooklyn crab salad followed by brownies (NY) to pie & mash and then rhubarb crumble trifle (LON). NY-LON’s website maintains it is open daily from 4pm to midnight, but some readers report finding doors locked mid-evening: best check first.
